If you’re familiar with phentermine, then you know it’s one of the most popular diet pills in the market. Apparently, this prescription pill works effectively in treating obesity. However, because it contains very strong ingredients, phentremine targets the central nervous system to suppress appetite, it also has some nasty side effects. If you really need to take it, I suggest you look up other alternatives like phentirmene, or ask your doc about it. I heard it’s as effective but without the side effects.
